Beit known that LRIOHABD E.v HARRIS, a citizen of the United States, residing in New York, borouffh of Manhattan, county and State of New lfork, have made a new and use#l ful Invention in WatervHeatei-s, of which the' My invention is directed articularly to iinrovements immeans for eating watery for uildings inwhich circulating AWater is heated primarysource of heat, as a ra e'or a boiler,. to and through a heating-charliiiier or boiler, usually located at some distance awayromV` the primary source ofhcat, suchfap aratus being in well-knotvh use inn; rivate"A euses, apartment-buildings, and the ke; i

It is a well-known 4fact, that with-,heating apparatus. of the ty e indicatedin-many instances during the cated '.te'r'mfo the -year the source of heat iscut olf so'that the rooms or apartments supplied withcirculating wa- My invention has for its obj ts,lfirst,'l the provision vof novel. sup lemetal heating means combined with suc a aratus,where eat4 the `entire supply of water may'lgbe heatedsfciently for general use thro g'hout n. huildngsec` ond, the provision o,v novel means whereby, in the event of the failure of the primary source of heat, as a range or=a bolier, such V supplemental source. may' be immediatelyput'into tion for use; third, the provision of means maybe automatically actuatedbl)T the lternperature -of the water in the mam 'heatingtherein at a definite temperature i'fourth, the provision of a novel water-heatln system adapted to heat waterfor use in bui dingsfin which system the source of heat is an inflam'- mablc gas and the heating means is in thc nature of one r more perforated tubular burners sustained inside of a heatin tube or tubes` in a heating-chamber and com ined with one: or more additional tubes sustained in the same heating-chamber and adapted to carry ofi' the products of combustion, the relation being such that a maximum heating efiect is obtained with-a minimum amount of combustible gas., l

The operation is as follows: The main sup. plyV ol' heal lieiug cutA ol by acock F in the pipe .E und theeoeks'whicli supply thegas :and th( water lor-'the burners and su iplemental lieiitiiig- -.lui=iiihi-.r A" having ieen turned in the proper direction, the gas ilow.

b iistionfroin the burners tothe outside ol the IIO inally the temperaturein the main chamber inglthrough the nozzles N is ignited at the perforations throughout the entire lengths ofthe tubular burners Kby the jets from the'pilot or lighting burnersN2, and the products of combustion pass downward-through the pipes EE into the chamber C2, again downward and into the lower ends of the outlet-pipes I in the direction of the arrows, thus causing said outlet-pipes to additionally heat the water in the supplemental heatingchaniber, said products of combustion finally emerging into the chamber C3 at the other end of the supplemental heating-chamber,

as shown, and passing outward by a pipe to the chimney or. some point exterior to the building. The regulation of the inflow of air u to the burners will beleiiected at the pleasure of the user bythe damperMf, the action of thespirally-disposed mixing devices S', givto the inflowing-gas Va spiral movement,

and-thereby effecting a thorough mixture of the ases with thel air before they enter the vtubuglarburners-K.- Consequently the water is heated the supplemental heatingchamber A and passes upward by reason of the inclined locatmnbf'such chamber vthrough vthe `outlet-'pipe C into the main heating- I chambenA, and Whenthe supplytherein 1s suiiiciently heated the'therinostatic device G automatically turnsg-thecock Pand cuts o f the supply ofgas the pipe J', thus' extinguishing the gas in thefnozzlesjN; The water circulatesin the usual manner through the building by. the -pipeC 'and as it cools' returns throughltbe return-pipes-D `and D. When A falls to a point'beyond the predetermined temperature, thethermostaticdevice G again opens the gascock '12 in the pipe J and alf lows the jets of thepilotor lighting burners N 2 to ignite the gas at .the tubular burners K', and so this action continues indefinitely.
